A 53-year-old man who was known as a "career flasher" was sentenced to more than 13 years in jail after pleading no contest to charges of exposing himself to a woman, the Associated Press reported.
San Francisco Police arrested Kenneth Ray Burton last year after he allegedly began to masturbate in front of a woman on a commuter train.
Burton already had two convictions of indecent exposure and six counts of sexual assault on his record before his latest arrest, San Mateo County Chief Deputy District Attorney Steve Wagsaffe told the AP.
Burton originally faced a maximum sentence of 25 years to life, but was commuted down after he agreed to plea no contest to five felony counts of indecent exposure.
